dent ,of Richmond, 001.1111151' .Orf Contra Cesta;

State of California, have Ainvented a new 2and yuseful Pavement Marker, of which the following is a specification.

The present invention relates to improvements in pavement markers and its particularvob'ject is to provide a portable means for facilitating the marking of streets, garages, public lplaces and the like for the purpose of providing safety zones, parking places for motor vehicles, .stop signals and the like. To paint these marks by the mere use of a vhand brush takes considerable time and is impractical since the marks very often have `to -be drawn across busy streets where the work is interrupted frequently by passing rstreet cars or motor vehicle-s. My device is designed to provide a kconvenient portable means for making these marks Y allowing the whole oper-ation to be vperformed by simply pushing the device over the pavement to be marked without interfering with the traliic to any considerable extent.

The preferred form of my invent-ion is shown in the yaccompanying drawings in which Figure 1 represents a longitudinal section through my device taken substantiallyalong line 1-1 of Figure V3, Figure 2 a side view of my device, Figure 3 Van enlarged vertical cross-section through the same taken along the center line of the device, Figure 4 a detail view of a portion of a track used in my device vand Figure 5 a detail side view of a modified form of a paint receptacle adapted to be substituted for the one shown in the principal form under certain conditions. )While I have shown onlythe preferred form of the invention it should be understood that various' changes or modifications may be madel within the scope ofthe claims hereto attached without departing from the spirit of the invention My device is supported oril two wheels (l) of rather large diameter, in the hubs (2) of which is supported an aXle (3), bushings (4) serving as bearing members. Grease may be admitted te the bearings through grease cups (6). The Wheels are provided with wide rims (7) and support on their axle the housing (8) comprisingside members (9) designed to cover the operative portions of the device and transverse members .(1.1) Gametime .the Side members The latter ane perforated eentrall-y Asolthat may be slipped over the reduced Iends ncf the axle and are held in Plac by rSleevemits (l2) :,thradedly engaging 'the said" rdiil ends whilecaps (13) `,adgapted to 2be screwed on the Lsleeve nuts serve to keep VutdLust and Othelmpuritesi .O11 the we .sonneries member' (11) is supported Aa receptacle (14) adapted 'to be filled with liquid paint lan pilletpenins (1,6) being provided with vplug (.17) V'ifi-ir Clesngthefseme float (lf) iSPIffer-ably disposed within the tankhaving afsteiiiv (19) secured thereon `which extends through fthe cap and indicates to the operator the paint level. A discharge pipe (20) commpnicates with the bottom of the receptacle and leads to within close 4proximity ofthepaveinent to be marked, adapted -to deliver the fli'qui-d paint in front of the rotar-y brush .(21) tatably supported in two hangers susn pended from the aXle and-normally held in a vertical position y means of a handle (23) pivotally engaging the shaft ion which the brushrotates and resting-withits upper end on one of the transverse connectingniembers (11) Ypreviously mentioned. plurality of notches (26) are prpvided in 'the lower face of the handlefadapted to engage the transverse member forholdingjthe handle against longitudinal motion. 'Ifo vlift the brusho-utvof engagement Vwith the pavement surface'it is only necessary to pull the handle upwardly and to engage the transverse member '(11) with a lower notch.

Rotary motion is imparted to the brush by means of a chain drive from one of the wheel hubs, a cog Wheel (28) fixed-to `the hub driving a transverse shaft (29,) supported in one of the hangers (22) through a i cog wheel (31) and a second cog Wheel (32) on the shaft (29) being operatively connected, through a chain (33), with a cog wheel (34) onthe shaft (24). The chainpasses around an idler (36) `supported on na `.pin (37) riding in a slot (38) inthe .hanger and forced away from theshaft (24) bya spring (39) which latter thus servfeiSf-.O-vhold the chain under tension while allowing the shaft (24) to ride downwardly in avvertical slot (41) in the hangerwhen the brush becomes smaller due to wear. The port area of the discharge pipe (20) is controlled by a suitable valve (42) adapted to -beshut and opened lby means of ;a v.rod (43) extendngel ing rearwardly and provided, at its extreme end, with a hand wheel (44).

To limit the lateralrange ont the brush and to provide a clean cut margin for the mark, l provide a link track on either side ot the brush, the tracks passing over and under the main wheels and rollers (eli) supported-on shafts (48) disposed in the front and rear ends, oi' the housing. A :trag- Inentary portion of the two tracks is shown in Figure t from which it will appear that each track consists oi a plurality ot flat plates (49) provided with marginal flanges (5l) which latterare pivotally connected as shown at (52), in the drawing. `When passing underneath the main wheels (l) they lie lat on the 'pavement surface and limit the range oi the brush laterally so as to produce a mark with straight marginal lines. ln case it is desired to provide periodical notices such as .Li/l0 Minutes in the mark this may be accomplished by connecting twoA corresponding links of the two tracks by a special link (53) having said notice cut into the same. Since this link would travel with the tracks it would he necessary to provide a receptacle that would not interfere with the travel oi the said link and for this purpose the receptacle (54) shown in Figure 5 might be substi tuted ior that shown in the main drawing.

ln the rear end oi my device l provide a Vmeans for making terminal marks such as a large circular spot comprising a brush (56) supported on a vertical rod (57) pivoted in a trame projecting from the rear end ot the main housingi 'lhe brush may he held out or contact with the pave ment surface hy pressing on a toot pedal (59) pivotally supported in the frame as shown at (6l) and engaging the rod between two collars (62). rllhe upper tace oi that portion or' the lever engaging the upper collar is shaped angular so as to hold the rod in an elevated position after the tree end ot the lever has been pressed down by the toot. To make a terminal mark the free end of the lever is lifted by striking the same with a ioot whereupon the brush may be rotated by means oi the crank handle Lateral angle irons (64) secured to the bottom of the housing tend to reinforce the same and brackets (66) are provided to prevent the device from tipping over sideways, and the whole device is pushed ton ward by means of handle (67).
